"Bruce Springsteen Week" on NBC's 'Late Night with Jimmy Fallon' concluded on Friday (March 2) with Springsteen performing three songs, two from his upcoming album, 'Wrecking Ball,' and a third from deep in the Springsteen archives that turned Studio 6B at 30 Rock into a joyous house party.

When Springsteen appeared on 'Late Night' in 2010 to promote the 'Darkness on the Edge of Town' box set, Fallon, as Neil Young, and Springsteen, dressed as a mid-1970s version of himself. The duo reprised the act in the show's opening, but with a few variations. This time Springsteen appeared in full 'Born in the U.S.A.'-era regalia, complete sleeveless denim vest, red bandana and shades. And instead of Willow Smith's 'Whip My Hair,' the pair sang LMFAO's 'Sexy and I Know it.'

After the first commercial break, Fallon brought out Springsteen for a chat. They began with a look at Bruce's outfits over the years, with Springsteen admitting, "There was a time when the entire band dressed as pimps" and telling a story about how he and guitarist Steve Van Zandt were kicked out of Disneyland because they refused to remove their bandanas.

Following the second segment, in which Springsteen discussed his legendary concerts and the story of how the crowd singing the first verse of 'Hungry Heart' became tradition, Springsteen stopped talking and began singing. We got our first look at the new incarnation of the E Street Band, complete with a 5-piece horn section, with a blistering rendition of 'Death to My Hometown,' tearing through the Celtic-influenced rocker with a passion the Dropkick Murphys could only envy.

Guitarist Tom Morello, of Rage Against The Machine and formerly of Audioslave, who played guitar on two songs on 'Wrecking Ball,' sat in with the band all night and contributed searing leads 'Death to My Hometown' and the second song, the gorgeous 'Jack of All Trades.'

As if the E Street Band wasn't already looking to become the third-most populous city in New Jersey, for the closer the Roots joined in for a roof-raising take on 'The E Street Shuffle' the opening cut off Springsteen's 1974 album, 'The Wild, the Innocent and the E Street Shuffle.' Fallon was seen banging away on a cowbell, clearly having the time of his life, and bringing the total number of musicians onstage to 24, including - seriously - 2 tubas. The coda has to be seen to be believed.
